This material presents the topic of modern machines. It combines the elements of mechanical theory, drafting skills and practical applications. The topics treated include: graphical analysis of machines in the areas of velocity and acceleration polygons, and the dynamics of cams, gears and intermittent motion mechanisms. The materials are presented in an action-oriented format combining many of the features normally found in a textbook with those usually associated with a laboratory manual.

This manual, along with the others in the Electromechanical Technology Series, is the result of six years of research and development by TERC, a national nonprofit, public service corporation with headquarters in Cambridge, Massachusetts. It has undergone a number of revisions as a direct result of experience gained with students in technical schools and community colleges throughout the country.
